he current code walks up the bus tree for an iommu, however it passes to the iommu_fn() callback the bus/devfn of the immediate child of the level where the callback was found, rather than the original bus/devfn where the search started from. This prevents iommu's like POWER8 (and in fact also Q35) to properly provide an address space for a subset of devices that aren't immediate children of the iommu. PCIe carries the originator bdfn acccross to the iommu on all DMA transactions, so we must be able to properly identify devices at all levels. This changes the function pci_device_iommu_address_space() to pass the original pointers to the iommu_fn() callback instead.
